Black Dragon Gold Corp.: Positive Preliminary Economic Assessment for Salave Underground

The Associated Press

VANCOUVER, British Columbia--(BUSINESS WIRE)--Feb 11, 2019--Black Dragon Gold Corp. (ASX/TSX-V: BDG) ("Black Dragon" or the "Company") is pleased to announce the positive results of the Preliminary Economic Assessment ("PEA") completed on its 100% owned Salave Gold Project ("Salave" or "Project") located in Asturias in northern Spain. The PEA is based on the recently completed Mineral Resource Estimate completed by CSA Global (See October 25, 2018 News Release). All figures are in United States Dollars unless otherwise stated.

The PEA demonstrates robust economics for an underground mining operation with a 14-year mine life.

Paul Cronin, Managing Director and CEO commented,

"The completion of the PEA is a major milestone on the path to development of the Salave Project and the metrics support our belief that Salave can potentially generate strong returns for shareholders. It forms the first step in our permitting process, presenting a new optimised process on a zero- discharge basis that minimises the visual and surface impact of the project.

The robust results of this PEA underline the potential economic viability of the current Salave resource to be mined over an initial 14 year mine life, and our successful drilling campaign last year indicates strong potential for growth in mine life at Salave.

This study supports that Salave can produce over 1.1Moz (560 kt of concentrate averaging over 59 g/t Au), providing a number of marketing options for export and refining, minimising the need for additional plant and equipment, and hence reducing the Project’s footprint. The relatively low upfront capex also opens alternative financing opportunities which will ensure that both shareholders and the local community benefit from the success of this Project."

MINERAL RESOURCE ESTIMATE

An updated NI 43-101 Mineral Resource Estimate, effective 22 October 2018 is included in this PEA and has been filed on SEDAR and the ASX market announcements platform (See October 25, 2018 News Release).

Notes: 1. Rounding may cause apparent discrepancies 2. Resource Estimate conducted by CSA Global of Perth Australia ("CSA") with an effective date of October 22, 2018. Classification of the MRE was completed based on the guidelines presented by Canadian Institute for Mining (CIM, May 2014), adopted for Technical Reports which adhere to the regulations defined in Canadian NI 43-101. The Mineral Resource Estimate was also prepared in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, 2012 edition ("2012 JORC Code"). 3. The Mineral Resource Estimate was first announced on 25 October 2018. Black Dragon confirms that it is not aware of any new information or data that materially affects the information in the previous announcement and that all material assumptions and technical parameters underpinning the Mineral Resource Estimate continue to apply and have not materially changed. 4. A cut-off grade of 2 g/t Au has been applied when reporting the Mineral Resource Estimate. 5. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability but do have reasonable prospects for eventual economic extraction. 6. The quantity and grade of reported Inferred Resources in this estimation are conceptual in nature and there has been insufficient exploration to define these Inferred Resources as an Indicated or Measured Resource. It is uncertain if further exploration will result in upgrading them to an Indicated or Measured Resource category, although it is reasonably expected that the majority of the Inferred Resources could be upgraded to Indicated Mineral Resources with further exploration. 7. The Mineral Resource Estimate underpinning the production targets in this announcement was prepared by a Competent Person under the 2012 JORC Code. 8. The title of the report is "Salave Gold Project Mineral Resource Update for Black Dragon Gold Corp.", with an effective date of October 22, 2018, and it was authored by Ian Stockton, B.Sc (Geol)., MAusIMM, FAIG, Dmitry Pertel, MSc (Geol), MAIF, GAA, and Galen White, B.Sc, FAusIMM, FGS.

POTENTIALLY EXTRACTABLE PORTION OF MINERALISATION FOR MINE PLANNING

The mine plan supported by the PEA demonstrates that approximately 81.1% of the total 2018 updated Mineral Resource tonnage is amenable to underground extraction. For purposes of mine planning, the potentially extractable portion of the Mineral Resources are comprised of 9.19 million tonnes at a diluted grade of 3.87 g/t Au, containing just over 1.1 million ounces of gold. The mineralised material modelled to be mined in the PEA contains Mineral Resources classified in the Inferred category (28%) that are too speculative geologically to have economic considerations applied that would enable them to be categorized as Mineral Reserves. These Inferred Resources will require further exploration and definition to meet the criteria to be classified as Indicated or Measured Mineral Resources before being considered for conversion to Mineral Reserves at the next level of detailed economic study.

MINE PLAN

Given environmental and community considerations, the PEA has only evaluated underground mining operations. The primary mining method selected for detailed analysis in this study was the vertical retreat mining ("VRM"). Sub-level stoping was considered as a secondary method applicable to specific vertical thin geometries (<15m length). Rock and paste fill will be used as backfill to maximize mining recovery.

The mine design was based on basic economic assumptions to create mineable stope outlines. A value of 2 g/t was assumed as mine cut-off grade. Mining dilution and mineralised material loss factors were also applied to each mining shape to reflect the selected mining method.

The mine production rate targets a 0.70 Mtpa of RoM. A conceptual mine layout was designed including stopes and development as illustrated in Figure 1, with 60m levels and 3 x 20m sub-levels. The total mineralised material from stopes, drives and sill pillar recovery (50%) will total 9.2Mt at 3.87 g/t Au.

A long term mine schedule was created integrating stopes and development as shown in Figures 2 and 3. Mineralised zones were sequenced to prioritise higher grades at lower operating costs.

MINERAL PROCESSING

In order to minimise potential social and environmental issues, processing of Salave mineralised material has been limited to crushing, grinding and flotation, with concentrates exported via local ports. Mine feed will be crushed on surface at a rate of 0.7 Mtpa, and then be processed via conventional SAG and ball milling followed by sulphide flotation and thickening.

The run-of-mine will feed a primary jaw crusher with a capacity of 400 t/h with a physical availability of 70% with design factor of 20%.

From an intermediate stockpile, the coarse material will feed the mill circuit which consists of a conventional SAG and ball mill configuration working in close circuit with the cyclones.

The flotation circuit consists of a number of cells of 300-400 m 3 capacity (9-10 cells of 40 m 3 each) with two conditioning tanks for pH stabilisation and reagents.

The final stage consists of tailings thickening to minimise the fresh water consumption and to re-cycle process water. A ‘paste’ thickener will achieve a product of 70-75% of solids.

Based on flotation test work conducted to date, it is assumed that 97% of the gold head grade will be recovered in the flotation concentrate that will be thickened, filtered and bagged for shipping to customers.

INFRASTRUCTURE AND TAILINGS

Power to the project is available from Tapia, which is linked to the Asturias main distribution grid, and an existing network of power lines enter the property that are connected to the Spanish national transmission grid. Water for both domestic and plant usage can be sourced from wells, the Porcia River (2.5km east of the property) or the reticulated water supply that is currently in place near the plant location.

A Tailings Management Facility ("TMF") will be constructed at surface for temporary storage of plant tailings. The paste and backfill of the mine will minimise the amount of tailings storage at surface, and various options for complete tailings disposal are being evaluated. The TMF design will involve water recovery in the processing plant and transportation to geo-membrane lined facility eliminating any risk for potential surface and ground water contamination.

Surface facilities to support the Salave Project will include an administration and engineering building, security, warehouse, fuel and explosive storage, fire protection, maintenance shops with a site design to accommodate for 50 full time staff.
